Alternative to a tact switch or incremental encoder to increase or decrease the value of a certain parameter.
Electrically, the potentiometer is a standard 245° linear taper with a 5% absolute linearity. The mechanical rest position corresponds to the physical middle position, hence to the central value of the output signal. Starting from there, the output value varies along the linear curve until reaching the corresponding end stop.
An alternative output signal to the above is an SPDT* configuration, with “on” positions at both mechanical end stops and “off” position in the central rest position. Mechanical angle option available: ±45°
